This environment fully depends on espressif® ESP32 projects, on that basis, we fixed the "variants" folder and "boards.txt", for the convenience of "Arduino + ESP" beginners and Heltec ESP32 series Dev boards users.

This development environment only includes the basic framework of ESP32, ESP32-S2, ESP32-S3, and ESP32-C3 MCU chips. NOT include the drivers or example code for on-board devices such as LoRa, OLED, Sensor, etc.

Major Update

• Development framework update to espressif ESP32 based on ESP-IDF v5.1
• Remove Heltec ESP32 series external devices and functional examples;
• Remove ESP32 Arduino LoRaWAN library;
• All Heltec ESP32 series boards relevant examples moved to the Heltec ESP32 library;
• Fix board definition and information;
• Add new boards.
